I guess either long or att goes from 0 to Pi only.

With SphericalPlot3D you can choose a color (or more general any list of
graphics directives) this way:


<<Graphics`ParametricPlot3D`

SphericalPlot3D[{1,color[long,att]},{att,0,Pi},{long,0,2Pi},Lighting->False]


With ParametricPlot3D it was:


ParametricPlot3D[{Sin[att]Sin[long],Sin[att]Cos[long],Cos[att],color[long,att]},
{att,0,Pi},{long,0,2Pi},Lighting->False]


Hope that helps
